Explanation of the hadith
This Hadīth shows the politeness of the Companions of the Prophet (may Allah's peace and blessings be upon him). They would sit in the Prophet's gathering wherever they could find a place, whether close to or far from the front. This is how one should behave when he enters upon a group sitting together. He should not proceed forward unless someone gives him his place or there is room for him in the front. That a person makes his way through a group that is sitting, as if he impels them to give way to him so that he sits in the front, is behavior that goes against the practice of the Prophet (may Allah's peace and blessings be upon him) and his Companions. Moreover, it indicates the person's arrogance and conceit.
